Abstract

This document generally relates to wireless communication systems that involve one or more intelligent reflecting devices. A plurality of second nodes that communicate with a first node may be grouped into node groups based on one or more communication parameters between the plurality of second nodes and an intelligent reflecting device. In turn, the first node may transmit signals to the plurality of second nodes via the intelligent reflecting device according to a time schedule based on the node grouping. In addition or alternatively, an intelligent reflecting device may include surface elements that are divided into multiple surface element regions. The first node may communicate with the multiple surface element regions independently in order to service the plurality of second nodes.
